FIREWORKS Filed Nov. 25, 1936 INVENTOR I MW R HEW Patented Aug. 30, 1938 UNETED STATES EXTENT QFFIQE 7 Claims.

This invention relates to fireworks and more particularly to skyrocket constructions.

Among the objects of the invention is to generally improve the construction of skyrockets and like types of fireworks which shall comprise few and simple parts which are easily assembled to form an attractively appearing structure, which shall be cheap to manufacture, and which shall be efiicientand practical to a high degree in use.

" Other objects of this invention will in part be obvious and in part'hereinafter pointed out.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the following claims.

In the accompanying drawing in which is shown one of the possible illustrative embodiments of this invention,

Figure 1 is a front elevational view of a skyrocket construction embodying the invention.

Figures 2 and 3 are enlarged cross sectional views taken on lines 2-2 and 3-3 in Figure 1.

Figure 4 is a cross sectional view corresponding to a cut taken on line 4-4 in Figure 2, and

Figures 5, 6 and 7 are front elevational views of the separated parts of the skyrocket, namely,

the cap, outer casing and shell, respectively,

shown disassembled, said cap and casing being shown collapsed for shipment or storage.

Referring in detail to the drawing, I0 denotes askyrocket type of firework constructed to embody the invention. Said skyrocket I0 is seen ggsfrom'Figure 3, to comprise a cylindrical type of shell I I which may be filled with a usual propelling charge C in the lower end Ila thereof and also may contain an explosive and colored illuminating display material (not shown) in the head s r end IIb. Said shell II and contents may be assembled in anysuitable manner well known in theart;

The charge. 0 is retained in the shell end IIa by a suitable plug closure I2 which is provided with an axial passage I2a through which a cord fuse I3 is inserted, a folded end I3a thereof extending into the charge C. A freeend I3b of said fuse I3 projects beyond the shell end I la for setting off the skyrocket.

,n The novel construction embodying the, invention will now be described. Applied over the filled shell II there is provided a casing I4 made of suitable sheet material, such as cardboard or the like. Said casing I4 preferably comprises a tapered tubular structure which may be collapsed for shipping or storage before assembly, as shown in Figure 6, and as here shown when applied over the shell is of hexagonal cross section. See Figure 2,

Said casing I4 has its lower end I4a sized to 55.. circumscribe the circular shape of the shell end Ila which snugly fits therein. The other or upper end lb of the casing I4 may be made with flaps Idc which are adapted to be bent inwardly toward the upper end III) of shell II, said flaps 101 I40 being so cut and shaped to slopingly embrace with the free edge Md of the shell end I Ib, as shown in Figures 3 and 6. Said flap edges I M may besecured to the shell end III) by a suitable adhesive I5. As a top cover on the upper or'lead- 15f: ing end of the skyrocket ID, a cap I6 is provided. Said cap I6 preferably is made of a sheet material similar to that of the casing I4 and before assembly can be collapsed as shown in Figure 5.

The cap I6 may be attached to the upper end 20 of the casing I4 with the shell end IIb fitted therein by suitable adhesive means I5a which also secures the flap edges Md to the shell end I I b, the outer surfaces of the flaps I 40 serving as a seat for the cap I 6 as shown in Figure 3. 25,1

Extending up along the casing I4 from the lower end I la thereof, a slot I! is provided, said slot I! being of sufficient width to receive the usual stick I8 which may be of square cross section.

As shown in Figure 3, the upper end of the stick 3055 I8 may be grooved as at I8a to engage with the inner edge portion of the slot IT. The side edges of said slot I1 abutting the stick I8 serves to retain the stick I8 against side movement with respect to the shell I I, as seen from Figure 3. 355'.

To fixedly secure the stick I8 in its assembled position, a binding wire I9, extending about the stick I8 and lower casing end Mb, is provided.' See Figures 1, 2 and 3.

An additional novel feature of construction in 401' the assembly of the fuse I3 in the filled shell is provided in having a member 20 extending from the lower casing end Mb. Said member 20 has an elongated opening 20a in the mid-portion thereof which is just large enough to permit the passage of the folded cord fuse I3, said opening 20a being located to register with the axial passage I'Za when the member 20 is positioned to extend over said bottom of the shell and Ila, as shown in Figures 3 and 4. The free end 2% of the member 20 may be inserted between the lower casing end I 4a and the shell end I Ib' to retain said member 20 in effective position shown in Figure 4.

The fuse I3 when inserted into the opening 20a and through the passage l2a has a short end 13a of the folded portion thereof within the opening 20a spring out of alignment with respect to the latter to act as a detent or stop against falling or being pulled out of the assembled position shown in Figure 3.

In practicing the invention, skyrocket l may be shipped knocked down that is, the filled shell ll, casing M, cap l6 and stick i8 may be separated for convenience and economy in packaging, shipping and storage. To assemble the skyrocket Hi, the filled shells II are inserted in the casings M with the upper ends Ha of the shells coinciding with the curved edges 14d. of the fiaps Me. By then dipping the upper shell ends Ilb into an adhesive supply for securing the edges Md of the fiaps Mc thereto, the outer surfaces of said flaps Mo are simultaneously coated with the adhesive Ia. The cap it is then applied in position. Said flaps l lc are thus made to serve as efiicient seating means for retaining the caps 56.

The sticks l8 may next be inserted into the slots 11 and the binder wire 19 clamped in place, as shown in Figures 1, 2 and 3.

The cord fuse l3 may then be inserted into the openings 29a. of the member 20, the latter being previously secured to extend across the bottom end of the shell Ma. and easing Ma. The fuse I3 is preferably made of a stiff, yet resilient material and an end i3a thereof folded over on itself so that the folded portion Iila thereof is sufiiciently long to extend well into the charge 0. The short end B1) of the folded portion 13a, after entering the opening 26a will spring slightly out :of alignment with respect to said opening 20a and will abut said member 20, as shown in Figures 2, 3 and 4. The skyrocket Hi will now be ready for use in the well understood manner.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
